Answer:
x = 3
y = 4
hey, I am not 100% sure of the certainty of my answers, I am using what I remember about that topic but I do not know if it is right or wrong, I hope I have helped you, I did what I could.
Step-by-step explanation:
-3x + 2y = 23
5x + 2y = -17
X solution:
(you cancel the y)
-3x = 23
5x = -17
(you combine all the values above with those below)
2x = 6
(solve the ecuation normaly)
x = 6/2 = 3
Y solution:
(you replace the x)
-3(3) + 2y = 23
5(3) + 2y = -17
-9 + 2y = 23
15 + 2y = -17
(you combine all the values above with those below)
6 + 4y = 6
(solve the ecuation normaly)
4y = 0
y = 4
(I do not really know if the answer here is 0 or 4 since when passing the 4 to divide it would be 0/4 and I do not understand very well how that is solved)
Answer:
1.049
Step-by-step explanation:
Divide 103 into 108
4) The first and second terms for both ratios need to be in the same order.
Step-by-step explanation:
Given ratio is:
16:36
In order to find any ratio equivalent to given ratio, the ratio can be divided by a number or multiplied to a number.
The equivalent ratio that is given: 72:32
If we multiply the given ratio by 2: We get 32:72
So,
Looking at the options we can conclude that the right answer is
4) The first and second terms for both ratios need to be in the same order.
